Abstract
Disclosed is an emergency power control cabinet which relates to the power electronic technology, in particular to a device which can provide emergency power for a firefighting power system. A single power supply output by a distribution room to the emergency power control cabinet is transferred into two branches, one is directly connected to a double-load emergency power supply auto-restart and the other is connected with a power rectifier; the output end of the power rectifier is also divided into two branches, one is connected with a diode, a charger, a switch B and an accumulator and the other is connected with a switch A, and the switch A and the switch B are connected by a lead. The switch A is respectively connected with two inverters 2 and 5; the inverter 2 is connected with the double-load emergency power auto-restart through a switch D and the inverter 5 is connected with a double-load emergency power auto-restart controller through a switch C. The utility model provides distribution and control for firefighting equipments such as a fire pump, a spray pump, a hydrant pump, an exhaust blower and a fan blower. Integrated with soft start, emergency power auto-restart and emergency operations, the utility model improves the reliability of system work, simplifies system links, reduces the occupying area of system field and is very applicable for various firefighting power loads.
Description
(1) technical field:
The utility model relates to power electronic technology, refers in particular to the equipment that can offer fire-fighting dynamical system emergency power.
(2) background technology:
At present, many important places are confession distribution and general each the one-tenth system of control appliance of the on-the-spot power-equipment in important places such as fire pump room, smoke evacuation machine room, air-supply machine room, Fire lift machine room particularly, constitute by duplicate supply prepared auto restart, two load prepared auto restart, three links of reduced voltage starting control cubicle, each link respectively is a platform independent equipment, what have merges into two equipment with three links, there is following shortcoming in this system: equipment is many, investment is high, independently each link all need be purchased separately and erection unit separately, has improved cost.Reliability reduces, and the equipment of each link is an independently hierarchy of control, and operation, maintenance workload increase, and each link control principle is independent, and link control circuit fault all can make system's paralysis suffer from arbitrarily, and failure rate improves.There is not on-the-spot emergency power supply function, under fire condition, if cut off the system front end network electric power for the personal safety that guarantees the personnel that put out a fire to save life and property when system's supply network fault or system power supply line fault or fire attack, system's paralysis is changed, totally unfavorable to falling into put out a fire to save life and property personnel's personal safety of the personnel that do not have enough time to escape in the scene of a fire and fire-fighting.
(3) summary of the invention:
The problem that the utility model exists at fire-fighting dynamical system emergency service and develop the emergency power supply control cubicle that integrates soft start, two load prepared auto restarts and on-the-spot emergency power supply.
The technical solution of the utility model is: be made of power rectifier, inverter, battery, two years prepared auto restarts, switchgear house power supply output single supply is to the emergency power supply control cubicle, transfer into two fens branch roads, one the tunnel directly connects two prepared auto restarts 3 that carry, one the tunnel connects power rectifier 1, power rectifier output one tunnel connects diode, charger 4, switch B and battery 6, and power rectifier is exported another road and met switch A, and lead connects between switch A and the switch B.Switch A connects inverter 2 and inverter 5 respectively, and inverter 2 footpath switch D connect two prepared auto restarts 3 that carry, and inverter 5 connects two prepared auto restart control device 7 that carry through switch C.Like this, electrical network just often, power rectifier output two-way DC power supply, the one tunnel is inverter 2 power supplies, another road is the battery charging, quits work during grid power blackout.2 of inverters are worked constantly at grid power blackout or load starting, output wideband transformation soft start power supply during load starting, and load starting finishes the back electrical network normally then deactivates, and then exports the 380/220V three-phase four-wire power as grid power blackout.Two years prepared auto restarts 3 two motors one worker one is equipped with, and when work drive motor or place loop fault quit work, standby motor was devoted oneself to work automatically.Inverter 5 is used to two prepared auto restart control device that carry that startup power supply is provided, and output 220V voltage is deactivated behind the proceed-to-send.Battery 6 just often is in charged state at electrical network, is in discharge behind the grid power blackout or prepares discharge condition.Switch A, B, C, D rationally change and adopt existing electronic technology just can realize.
The beneficial effects of the utility model are: according to the character of fire-fighting power-equipment work; characteristics and actual needs; to fire pump; spray pump; the water curtain pump; induced-draft fan; fire-fighting equipments such as forced draft fan provide distribution and control appliance; this fire-fighting dynamic control device collection soft start; the function of prepared auto restart and emergency is in one; make the control of fire-fighting dynamical system; protection; distribution and emergency realize integrated; intelligent; improved the reliability of system works; simplified system's link; system's investment and failure rate have been reduced; reduce the floor space of system for field, be very suitable for all kinds of fire-fighting living loads.
(4) description of drawings:
Figure is the utility model circuit diagram.
(5) embodiment:
This emergency power supply control cubicle as shown in the figure, the connection between power rectifier, charger, battery, inverter, two years prepared auto restarts and switch A, B, C, the D is as described in the scheme, integral body places control cubicle.Working method: the electrical network normal power supply, if load is in and treats operating state, then switch A and rectifier join; B and charger join; C and inverter 5 join; D and inverter 2 join.When two years prepared auto restart control device of fire-fighting control signal input, system enters the soft start state automatically, and when load starting finished, switch D and C changed simultaneously, and inverter 2 and 5 is deactivated, and system switches to operation under the electrical network.If electrical network cuts off the power supply for some reason in the running, then switch A, B, C, D change simultaneously, make system change the emergency power supply power supply state over to.Switch C reclosing is to automatic control cabinet bus after changing successfully, and inverter 5 is deactivated.Electrical network is stopped power supply, and all in preparing discharge position, D and C all are in the ready to start position for switch A and B.If this moment, two prepared auto restart control device that carry received system activation signal, then whole system can begin self-starting under the emergency power supply power supply state, and when soft start finished, switch C was converted to automatic control cabinet bus, and system enters normal operating condition.If this moment power system restoration normal, then switch ABCD changes simultaneously, change the mains supply state over to after, switch C is forwarded to automatic control cabinet bus again.Splendid through experiment effect.
